The GP Reader app connects an Android phone or tablet to RIOT's BTDL Bluetooth SDI-12 Data Logger, for example to log GroPoint in-ground soil moisture multi-segment profile sensors. Connect to the BTDL unit to configure measurements, download data, or display realtime soil moisture and soil temperature data on the screen.
Requires Bluetooth 4.0 (BLE) wireless connectivity hardware
GP Reader helps farmers, park and golf course managers to precisely monitor soil moisture at several levels of root depth. This allows for the most efficient irrigation and water conservation possible.
The Gro-Point Reader app works with RIOT's in-ground SDI-12 soil moisture profile sensors connected to the BTDL unit.
